1975年,我们先后学习了陕晋两省、广东信宜县、广西巷梧县修建水坠坝的经验,结合我区自然特点,开展了非均质水坠坝的试验研究工作。由于非均质水坠坝适合本地区土质等自然条件,因此得到较快的发展,目前已建24座非均质水坠坝,其中中型水库4座。最大坝高59.5米,最大库容5020万立米。 非均质水坠坝,是将高浓度泥浆冲填到坝面上的上下游坝坡后,人为地控制其流向和加水稀释分选,使坝体形成坝壳区、过渡区和中心防渗区。为了排除表面水、固结水和多余的粘粒、胶粘,以控制坝体各分区的
In 1975, we successively studied the experience of building water fall dam in Shanxi and Jin provinces, Xinyi county of Guangdong province and Xiangwu county of Guangxi province. Based on the natural characteristics of our district, we carried out experimental research on heterogeneous water fall dam. As a result of heterogeneous water fall dam suitable for the natural conditions such as the soil quality in this area, it has been developed rapidly. At present, 24 non-homogeneous water crashes have been built, of which 4 are medium-sized reservoirs. The maximum height of 59.5 meters dam, the largest storage capacity of 50.2 million cubic meters. Heterogeneous water-crashed dams, which are filled with high-concentration mud to the upper and lower dam slopes on the dam surface, artificially control the flow direction and dilute with water to make the dam body form a dam shell area, a transition zone and a center seepage prevention Area. In order to rule out the surface water, water and clay consolidation, the glue to control the various parts of the dam
